Worth knowing
Rules that come up in this work
The 60-day property CGT return
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Record keeping
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
The trading and property allowances
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
Questions
R&D Tax Credits questions from Isle of Dogs
Why do you charge a fixed fee rather than a percentage?
Percentage fees reward inflating the claim, which is exactly what HMRC's campaign targets. A fixed fee means our only interest is a claim that is right. For most small company claims £999 is also considerably cheaper than the 15% to 30% of benefit that contingent advisers charge.
How long does a claim take to pay out?
HMRC aims to process 85% of claims within 40 days but the compliance campaign has lengthened this for many. Relief reducing a Corporation Tax bill takes effect when the return is processed; payable credits are paid to the company's bank account. We track the claim and chase HMRC if it stalls.
What is the Additional Information Form?
Since August 2023 every R&D claim must be accompanied by a form submitted to HMRC before the CT600, giving project descriptions, cost breakdowns, the named senior officer responsible and any agent involved. Claims without it are removed from the return. We complete and submit it as part of the £999 fee.
What is the advance notification requirement?
Companies that have not claimed in the previous three accounting periods must notify HMRC of their intention to claim within six months of the end of the period. Miss it and the claim for that period is lost entirely. We check your position at the eligibility stage and file the notification as part of the service.
What costs qualify?
Staff costs including employer NI and pension for time spent on R&D, externally provided workers at 65%, subcontracted R&D at 65% with new rules on who claims, software licences, cloud computing and data costs, consumables transformed or used up in the R&D, and some clinical trial payments. Capital spend, rent and marketing do not qualify.
How much is the relief worth under the merged scheme?
For accounting periods starting on or after 1 April 2024 the merged scheme gives a 20% expenditure credit, taxable, so worth around 15% to 16.2% of qualifying spend net of tax. Loss-making companies spending at least 30% of total expenditure on R&D can claim the enhanced intensive rate, worth up to 27%.
